ABSTRACT
Objective To make a reasonable evidence-based nursing scheme for the oxygen non-humidified of continuing nasal cannula oxygen therapy. Method Adopting the JBI clinical evidence application system, make sure the evidence baseline investigated before application, used during clinical application, and reviewed after application. Based on the now available best evidence, making examination standard and apply it to clinical care. During the application of evidence, 81 continuing low-flow (oxygen flow≤4L/min) nasal cannula oxygen patients were taken. Making assessment on the experiment group(oxygen non-humidified) and control group (oxygen humidified) in three aspects: the comfort level and effect of oxygen therapy, and humidification bottles contamination. Results During the application of evidence, the difference between experiment group and control group shows no statistical significance (P>0.05);the experiment group in oxygen therapy operating time was (162.93±40.18) s, the control group operating time was (258.60 ± 56.97) s, the difference of two groups in shows statistical significance (t=8.752, P<0.01). Conclusion The continuing low-flow (oxygen flow≤4L/min) nasal cannula oxygen therapy do not need humidification. And the clinical application of this best evidence standardizes the clinical nurses oxygen nursing behavior, reduces the nursing cost and enhances the quality of clinical nursing.
ABSTRACT
PURPOSE: The purpose of this study was to provide a basis for non-humidified low flow oxygen by nasal cannula and to provide a guide for consistent care in nursing practice. METHODS: A methodological study on the development of guidelines with experts' opinions on collected items, framing PICO questions, evaluating and synthesizing texts which were searched with the key words (low flow oxygen, nasal cannula, humidification of oxygen, guideline) from web search engines. RESULTS: Of the 45 researched texts on the web, 9 texts relevant to the theme were synthesized and evaluated. All patients with humidified or non-humidified oxygen therapy reported that they had no discomfort. CONCLUSION: The results indicate that there are no tangible grounds for patients' perceived differences between the humidified and non-humidified oxygen under 4L/min supplied by nasal cannula. with oxygen. Therefore, non-humidification oxygen therapy is strongly advised when suppling under 4L/min oxygen by nasal cannula (recommended grade A).
